Description

Technical Field

[0001] The utility model relates to the technical field of hardware processing, in particular to an adjustable punching device for processing hardware products. Background Art

[0002] During the processing of metal sheets, punching and drilling are common processing requirements. However, if the existing metal sheet punching and drilling devices are not firmly fixed to the metal sheets during the punching and drilling process, it is very easy to cause deformation around the target hole, causing the target hole to also deform, thereby deteriorating the effect of punching and drilling, and may also cause the hardware sheet to be scrapped.

[0003] For example, a metal plate punching and drilling device disclosed in publication number CN218575610U, after the pressing plate presses the metal plate tightly, the motor 2 is turned on to drive the threaded rod 1 and the threaded rod 2 to rotate synchronously, so that the two sets of clamping plates move toward each other until the clamping plates abut against the metal plate, thereby completing the secondary fixation of the metal plate in the horizontal direction.

[0004] However, the above-mentioned clamping structure is less practical when used, because the four groups of clamping plates in the clamping structure are fixed by horizontal movement, and when the user punches a point other than the center of the hardware plate, the two groups of clamping plates will move relative to each other, which results in the two groups of clamping plates being unable to fix both sides of the hardware plate well, thereby reducing the practicality of the device; in view of this, we propose an adjustable stamping device for hardware product processing. Utility Model Content

[0005] The purpose of the utility model is to provide an adjustable punching device for processing hardware products to solve the problems raised in the above background technology.

[0006] 4. The repairing kit for automotive dents, according to claim 1, wherein a bottom of the foot stand comprises a through-hole, and the two foot pieces comprise two bosses, wherein the bosses comprise a through-hole, a screw bolt, and a nut. The bosses comprise a through-hole, a screw bolt, and a nut. The bosses comprise a through-hole, a screw bolt and a nut.

[0007] Preferably, the protective structure includes a positioning cylinder fixedly installed on both sides of the clamping plate, the inner wall of the positioning cylinder is slidably connected with a moving rod, the side wall of the moving rod is fixedly installed with a contact plate, a return spring is arranged on the surface of the moving rod, and the side wall of the clamping plate is fixedly installed with a contact switch.

[0008] Preferably, the contact switch is connected to a motor signal.

[0009] Preferably, a rubber plate is fixedly mounted on the side wall of the contact plate.

[0010] Preferably, one end of the return spring is fixedly connected to the side wall of the positioning cylinder, and the other end of the return spring is fixedly connected to the side wall of the contact plate.

[0011] Preferably, the pad is configured as a square structure.

[0012] Compared with the prior art, the utility model provides an adjustable punching device for processing hardware products, which has the following beneficial effects:

[0013] 1. The adjustable stamping device for hardware processing can facilitate the relative movement of four groups of clamping plates in four directions by setting an adjustment structure. The sleeve is driven to move up and down by the rotation of the screw. The movement of the sleeve drives the four groups of sliders to move inside the slide groove, and then drives two of the four groups of clamping plates to move to fix the two sides of the hardware plate, thereby improving the practicality of the device.

[0014] 2. The adjustable stamping device for hardware processing is provided with a protective structure to facilitate the protection of the side wall of the hardware plate. When the clamping plate moves, the contact plate of the side wall will also move. When the contact plate contacts the side wall of the hardware plate, the contact plate will be squeezed as the clamping plate continues to move, so that the contact plate moves inside the positioning cylinder through the moving rod of the side wall and contacts the contact switch, thereby avoiding damage to the hardware plate caused by excessive movement of the two sets of clamping plates during clamping.

[0021] Specifically, the adjustment structure 3 of the technical solution of the utility model includes: a device cavity 31, a slide groove 32, a screw 33, a motor 34, a slider 35, a sleeve 36, a connecting rod 37, and a clamping plate 38.

[0022] In one embodiment of the present invention, an adjustment structure 3 is provided so that the four groups of clamping plates 38 can be conveniently moved relative to each other in four directions. Before processing, the user can place the metal sheet on the upper surface of the pad 6, and then before punching and drilling, the user can start the motor 34 to rotate forward and drive the screw 33 to rotate forward. The forward rotation of the screw 33 drives the sleeve 36 to move downward, and the sleeve 36 moves downward to drive the four groups of connecting rods 37 on its side wall to move. The movement of the connecting rod 37 drives the slider 35 hinged thereto to move inward inside the slide groove 32, thereby driving two of the four groups of clamping plates 38 to move to fix the two sides of the metal sheet, thereby improving the practicality of the device.

[0023] Please continue reading Figure 1-Figure 4 The protective structure 4 includes a positioning cylinder 41 fixedly installed on both sides of the clamping plate 38, a moving rod 42 is slidably connected to the inner wall of the positioning cylinder 41, a contact plate 43 is fixedly installed on the side wall of the moving rod 42, a return spring 44 is arranged on the surface of the moving rod 42, a contact switch 45 is fixedly installed on the side wall of the clamping plate 38, the contact switch 45 is connected to the motor 34 signal, a rubber plate 10 is fixedly installed on the side wall of the contact plate 43, one end of the return spring 44 is fixedly connected to the side wall of the positioning cylinder 41, and the other end of the return spring 44 is fixedly connected to the side wall of the contact plate 43. By setting up the protective structure 4, it is convenient to do the side wall of the hardware plate For protection, when the clamping plate 38 moves, the contact plate 43 on its side wall will also move. When the contact plate 43 contacts the side wall of the metal plate, it will stick to it. At this time, as the clamping plate 38 continues to move, it will squeeze the contact plate 43, so that the contact plate 43 moves inside the positioning cylinder 41 through the moving rod 42 on its side wall. At this time, the contact plate 43 will squeeze the reset spring 44, and when the contact plate 43 moves, it will contact the contact switch 45, so that the motor 34 will no longer work, thereby avoiding the two sets of clamping plates 38 from moving too much during clamping and causing damage to the metal plate.

[0024] During operation, the user can place the metal plate on the upper surface of the pad 6, then start the motor 34 to rotate forward and drive the screw 33 to rotate forward, and the forward rotation of the screw 33 drives the sleeve 36 to move downward, and the sleeve 36 moves downward to drive the four groups of connecting rods 37 of its side wall to move, and the movement of the connecting rod 37 drives the slider 35 hinged thereto to move inward inside the slide groove 32, thereby driving two groups of clamping plates 38 of the four groups of clamping plates 38 to move to contact and fix the two sides of the metal plate, and when the clamping plate 38 moves, the contact plate 43 of the side wall will also move. When the contact plate 43 contacts the side wall of the metal plate, it will be tightly attached to it. At this time, as the clamping plate 38 continues to move, it will squeeze the contact plate 43, so that the contact plate 43 moves inside the positioning tube 41 through the moving rod 42 of its side wall. At this time, the contact plate 43 will squeeze the reset spring 44, and when the contact plate 43 moves, it will contact the contact switch 45 so that the motor 34 will no longer work, thereby completing the clamping work, and then the user starts the electric push rod 7 to drive the pressure plate 8 to move downward for secondary fixation, and then starts the drilling structure 5 to perform punching and drilling work.
